FEATURES

LTC1450/LTC1450L

Parallel Input, 12-Bit

Rail-to-Rail Micropower

DACs in SSOP

DESCRIPTION

The LTC

1450/LTC1450L are complete single supply, rail-

to-rail voltage output, 12-bit digital-to-analog converters

(DACs) in a 24-pin SSOP or PDIP package. They include an

output buffer amplifier, reference and a double buffered

parallel digital interface.

The LTC1450 operates from a 4.5V to 5.5V supply. The

output can be pin strapped for 4.095V or 2.048V full-scale.

It has a 2.048V internal reference.

The LTC1450L operates from a 2.7V to 5.5V supply. The

output can be pin strapped for 2.5V or 1.22V full-scale. It

has a 1.22V internal reference.

The LTC1450/LTC1450L offer true stand-alone perfor-

mance. In addition, the reference output, high and low

reference inputs and gain setting resistor are brought to

pins for maximum flexibility.
